The effect of injection-stream turbulence on film cooling effectiveness and heat transfer coefficients
Abstract
Experiments were performed to investigate the effect of the injection stream turbulence on the film cooling process downstream of a two-dimensional film cooling slot. Results indicate that increases in the injection-stream turbulence intensities not only decrease the adiabatic film cooling effectiveness, but also increase the heat transfer coefficients; both effects reduce the film cooling performance in the mixing region.
